p38, Mpk2, D-p38a, p38 MAPK, Dp38
p38a serine/threonine protein kinase - involved in response stress including heat shock, oxidative stress and starvation - activates its downstream component Atf-2 that in turn regulates Duox expression
Low-frequency RNA-Seq exon junction(s) not annotated.
Gene model reviewed during 5.47
Dually phosphorylated on Thr-184 and Tyr-186, which activates the enzyme.
The TXY motif contains the threonine and tyrosine residues whose phosphorylation activates the MAP kinases.

Please Note FlyBase no longer curates genomic clone accessions so this list may not be complete
Please Note This section lists cDNAs and ESTs that fall within the genomic extent of the gene model, which may include cDNAs and ESTs of genes within introns, or of overlapping genes. Please see GBrowse for alignment of the cDNAs and ESTs to the gene model.
For each fully sequenced cDNA the DGRC maintains various forms of the cDNA (e.g tagged or untagged) in several different host vectors for subsequent cloning and expression in Drosophila and Drosophila cell lines.
Renamed from 'Mpk2' to 'p38a' to: i) make nomenclature consistent between p38 genes; ii) reflect the preferred usage in the literature; iii) reflect the preferred symbol used in the first peer-reviewed papers to characterize the gene (FBrf0100059, FBrf0102625).
Relationship of "Mpk2" to "Erk-B" not known.
Null mutants are homozygous viable with no developmental defects, though show susceptibility to some environmental stresses including heat shock, oxidative stress and starvation. Immune response profile of Mpk2 mutants is largely normal.
Mpk2 is cloned and sequenced from a neoplasmic l(2)mbn cell line. Study of the protein and its function reveals that similar osmotic stress-responsive signal transduction pathways are conserved in yeast, Drosophila and mammalian cells.
